If only we could get that kind of performance out of our new cars. [Reply]  [No Email]

Town friends will stop in here from time to tome and see a shiny 4020 setting here in the shop ans say "Why is a tractor that new being worked on" when I tell them it"s 45 years old they can"t believe it,,their 4 year old cars are in the shop a couple times a year...

When the check valve gets plugged low pressure builds in that area and causes the engine to idle down and stop, some times they will run for a few minutes and stop, some times they will stop right away. Removing the check valve don"t fix the problem,it just lets you have a little time to get the job at hand done and then rebuild the pump. The newer replacement coupling, last a lot longer, and the new style pumps don"t use this kind of coupling. You need to remember, some of these old pumps are 40 years old or so... [Reply]  [No Email]
